VALVE MECHANISM FOR VAPOR-STOVE BURNERS.

SPECIFICATION forming part of Letters Patent No. 376,518, dated January17, 1888.

(No model.)

To all whom it may concern.-

Be it known that we, DAVID E. DANGLE and HENRY BUPPEL, of Cleveland, inthe county of Cuyahoga and State of Ohio, have invented a certain newand Improved Valve- Mechanism for Vapor-Stove Burners; and we do herebydeclare that the following is a full, clear, and complete descriptionthereof.

The nature of our invention relates to the means emploped foroperatingthe needle valve in connection with the vapor generator and burner, ashereinafter set forth and described.

To enable those skilled in this art to understand said invention,reference Will be had to the following specification and to the annexeddrawings.

Like letters of reference refer to like parts in the several views. I

Figure 1, Plate 1, is a front elevation showing the improvement inconnection with a V3.7 por generator and burner and parts thereof insection. Fig. 2, Plate 2, is a side elevation. Fig. 3, Plate 1, isadetached detail in perspective.

The oil-induction pipe A is connected with a reservoir in the usual way,and its upper end is in open attachment with the vapor generator orretort B, which forms an annular tube around the chamber of thevapor-burner O, of which 0 is the semi-spherical wall and O theburner-cap. The vapor from the generator passes through the pipe D, Fig.1, into the chamber of the needle-valve casing E,and from theneedle-valve opening a it passes through the pipe F to the burner G. aThis burner consists of an undulating or curved tapering cap withperforations, mounted upon a flat base fastened to the pipe F. The pipeDis attached to the generator B by a screw-connection to the tubular bossH. More than one of such connections may be made with the generator forconveying vapor to the several burners. The pipe I has also a threadedattachment at J with the generator, by which means the vapor istransmitted through the pipe I to the needle-valve chamber in thecasingK fromthe generator B.

Connected to the casing K is a cup, L, for the reception of oil toproduce the primal flame in the initial vaporizing of oil in retort orgenerator B.

Projecting from the casing E is a bracket,M, Fig. 1, on the return orarm 0 of which is movably fitted the sleeve d of the adjustable bracketN in a line parallel with the needle valve and stem. From the upper partof this bracket extends a bearing, 0, Figs. 1 and 2, at right angles, ornearly so, with the line of the needle-valve, the stem I of which isseen in Fig. 1. supported in this sleeve 0, and the cam R is fastened tothe end of the said cainrod.

The needle-valve stem P is attached to a cam-yoke, S, Fig. 8. This yokeis rectangular in form,with a corresponding central space, S, in linewith the needle-valve stem. In this space S is arranged the cam oreccentric R to operate the yoke S by means of the rodQ, so as to cause areciprocating movement to the yoke and valvestem in opening and closingthe needle-valve in the casing E, of which a, Fig. 1, is thevalve-opening. When the cam R is turned to the position 6, as indicatedin Fig. 1 bydotted lines, the valve at a. is then closed, cutting oilthe vapor from the burner. On turning the cam to the position f the yokeis moved back thereby a distance indicated at g. The change of positionsor movements of the cam and yoke are indicated by dotted lines efg,Fig. 1. The valve being thus opened admits of the passage of vapor fromthe generator or retort B to the burnerG, as before stated.

From the rear angle-arm of the yoke S projects a stud, T, which slidesin the slot U in the end of the adjustable bracket N, Figs. 1 and 2.This stud and slot act as a guide and support for the yoke, and alsodetermine the The cam-rod Q is journaled and travel of the needle-valvein closing it, according to the position of the bracket on the arm 0, asthe stud T, when moved in contact with the closed end of the slot U, asseen in Fig. 1, arrests the forward movement of the needlevalve. Thisforward movement or stroke of the needle-valve may be more or less,according to the position of the bracket N upon the arm 0. The moving ofthe bracket N upon the arm 0 in direction of the arrow causes theeccentric or camto move the yoke with the needle valve connection,correspondingly as the sweep of the cam less than a full stroke isarrested at the desired point of closing the valve by the stud T beingbrought in contact with the closed end of the slot U,which prevents theneedle-valve from being forced or unduly pressed into the valve-openinga. This arresting of the valve from being unduly forced into the valveseat or opening causes the valve and seat to endure much longer withoutleakage than when used in the ordinary way. In case the needle valve andseat become so worn as to leak, it may be remedied by moving indirection of the arrow the bracket N on the arm a sufficiently to causethe cam R to press the valve more tightly on its seat. The open end ofthe slot U admits of the needle-valve being drawn back from its seat thefull stroke of the cam.

On first adjustmentof the needle-valve mechanism described, the fulleccentric stroke of the cam R is restricted by means of the stud T beingbrought in Contact with the closed end of the slot U, as beforestated,by which means the valve-openingis relieved from undue pressureof the needle-valve.

In case of leakage by use, the full stroke of the cam not beingsufficient to arrest the leak on closing the valve, then the bracket Nmay be moved on the arm a in direction of the arrow, thereby exertingmore force by the cam without its full stroke to close the valve moreeffectually.

The arm 0 not only admits of the bracket N moving longitudinallythereon, but it also permits an axial and lateral or vibratory movementfor adjusting the cam and yoke in position with relation to the bracketand rod Q, as shown in Figs. 2, 3, in which it will be seen that the camis movably arranged in space S, between the bracket N and yoke. Thebracket is retained in its adjusted position by means of the set-screwV, which passes through the sleeve (1 and fastens upon the arm 0.

In the preceding description the needle valve mechanism has referredmore particularly to a horizontal needle-valve. The improvements are,however, applicable to a needle-valve in an angular or perpendicularposition. In Fig. 1 both the perpendicular and horizontal positions ofthe valve mechanism are represented and arranged substantially in thesame way, the difference being in position only; and Fig. 2 is adifferent view of essentially the same construction and adjustment ofthe needle-valve devices and attachments as that shown perpendicular] yin Fig. 1.

To avoid prolixity the specification more particularly refers to theimprovements applied to the horizontal valve.

'What we claim as our invention, and desire to secure by Letters Patent,is-

1. In a vapor-burner, the adjustable bracket N, movably connected inrelation to the arm 0, and having a slot, U, closed at one end, a yoke,S, with a stud engaging said slot, a cam arranged in connection withsaid yoke in central line, or nearly so, with the needlevalve, and acam-rod having its support in the bracket for operating said cam for themovement of the needle-valve, substantially as described, and for thepurpose set forth.

2. The combination, with a vapor-burner, ot' a cam, It, movably arrangedin connection with the yoke S, for operating the needle-valve by meansof a rod having its bearing in a bracket on one side of said cam, and aslot at one end for the reception of a stud projecting from theyoke andof an arm, a, for carrying said bracket and to admit of its longitudinaland axial movement thereon, substantially as and for the purposespecified.

8. The combination, with the bracket N,l1aving an axial and longitudinalmovement upon the arm 0 and attached thereto in a line parallel with theneedle-valve, of a cam arranged within the yoke, connected with the stemof the needle-valve and operating conjointly in connection with avapor-burner, substantially as and for the purpose set forth.

In testimony whereofwe affix our signatures in presence of twowitnesses.
